Weather Forecast:
Rainfall of 10 to 15 mm is forecasted today, May 14. An additional 5 to 10 mm of rain is forecasted tomorrow, May 15, 2019.

Environmental Conditions:
Water levels along the lower Ottawa River from Chats Lake to the Grenville/Hawkesbury area have stabilized and will slowly recede in the coming weeks.

Risks:
All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk as snowmelt continues along the upper Ottawa River.

South Nation Conservation (SNC) and partners added another 310 trees to the Eastern Ontario landscape through a planting event in the Township of Alfred Plantagenet on Saturday, May 11, 2019.

SNC teamed up with youth from the 58e St-Bernard de Fournier Scouts group to refill an existing tree buffer near Curran, Ontario. Local scouts worked together to plant 290 White Spruce seedlings and 20 Red Osier Dogwood shrubs, contributing to the area’s forest cover and wildlife habitat.

Weather Forecast:

Rainfall amounts of 10 to 15 mm is forecasted today, May 10.

Environmental Conditions:
Water levels along the Ottawa River from Mattawa to Montreal are increasing due to recent precipitation and spring runoff upstream in the Ottawa River basin.

Locations from Point Gatineau down to the Grenville/Hawkesbury area could see water levels rise, without exceeding the initial peak observed last week, depending on the amount of precipitation received.

Weather Forecast:
Rainfall of 10 to 15 mm is forecasted for today, May 10, 2019.

Environmental Conditions:
Lake Ontario’s levels are increasing due to significant precipitation, reduced outflows, high inflows from Lake Erie, and spring runoff.

Water levels between the Iroquois Dam and Moses-Saunders Dam in Cornwall have been increasing due to reduced outflows at the Moses-Saunders Dam. Gates at Iroquois were lowered to supress water levels and keep them below flood values in the area.

Weather Forecast: Rainfall amounts of 20 to 50 mm are possible Thursday morning into Friday as a large low-pressure system moves into the area Thursday, May 9, 2019.

Environmental Conditions: Ottawa River water levels are currently decreasing. Forecasted rainfall could cause levels to increase again but are not expected to exceed initial peeks observed last week. Locations from Point Gatineau down to the Grenville/Hawkesbury area could see water levels stop decreasing depending on precipitation received.

Weather Forecast:
Rainfall of 10 to 20 mm is forecasted today, May 3. An additional 5 mm of rain is possible on Monday, May 6, 2019.

Environmental Conditions:
Water levels along the lower Ottawa River have peaked and are expected to remain stable and slowly decline over the next few days.

Risks:
All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk as snowmelt continues along the upper Ottawa River.

Weather Forecast:
Rainfall of 15 to 35 mm is expected today, May 1, 2019 in the Ottawa River basin.

Environmental Conditions:
Water levels along the lower Ottawa River are increasing due to spring runoff upstream in the Ottawa River basin. Runoff from snowmelt, precipitation and saturated soil has swollen most of the Ottawa River’s tributaries.

Risks:
All flood-prone areas along the Ottawa River from Lac Coulonge to the Montreal Archipelago are at risk.

Weather Forecast:
Rainfall of 15 to 35 mm is forecasted for today, May 1, 2019.

Environmental Conditions:
Lake Ontario’s levels are increasing due to significant precipitation, reduced outflows, high inflows from Lake Erie, and spring runoff.

Water levels between the Iroquois Dam and Moses-Saunders Dam in Cornwall have been increasing due to reduced outflows at the Moses-Saunders Dam. Gates at Iroquois were lowered to supress water levels and keep them below flood values in the area.

This statement is an update to the Flood Outlook statement issued April 24, 2019.

Weather Forecast:
Rainfall of 15 to 35 mm is forecasted for today, May 1, 2019.

Environmental Conditions:
Since April 24, SNC rain gauges have recorded approximately 10 to 20 mm of rain.

Soil across the jurisdiction is saturated, and there is no snowpack remaining.

Water levels across the watershed have decreased and are returning to normal ranges. Levels in some parts of the jurisdiction remain above average for this time of year.

South Nation Conservation (SNC) works with 16 member municipalities in Eastern Ontario to deliver local environmental programs and service that improve water resources.

SNC maintains 20,000 acres of community forests and plants over 120,000 trees every spring. 

“Conservation Authorities are local environmental organizations with boots on the ground, fingers in the soil, and hands in the water,” adds Bill Smirle, SNC Chair. “SNC helps the Province and municipalities achieve shared environmental objectives while supporting safe and sustainable growth.”
